3.1 Introduction

3 3
This chapter describes the considerations necessary to
integrate the frequency converter into a system design.
The chapter is divided into 4 sections:
•
Ambient operating conditions for the converter
including environment, enclosures, temperature,
derating, and other considerations
(chapter 3.6 Ambient Conditions)
•
Input into the converter from the mains side
including power, harmonics, monitoring, cabling,
fusing, and other considerations
(chapter 3.2 Mains Input)
•
Output from the converter to the motor including
motor types, load, monitoring, cabling, and other
considerations (chapter 3.3 Motors)
•
Integration of the converter input and output for
optimal system design including converter/motor
matching, system characteristics, and other
considerations (chapter 3.4 Frequency Converter/
Options Selections).

VLT DriveMotor FCP 106 and FCM 106 Design Guide
3.1.1 FCM 106 - Integrated Frequency
Converter and Motor
The Danfoss VLT frequency converter integrated onto the
asynchronous or permanent magnet motor enables speed
control in a single unit.
The FCM 106 is a very compact alternative to a central
solution where the frequency converter and motor are
installed as separate units.

•
Factory-set adaption between FCM 106 and the motor
gives precise and energy efficient control in addition to
eliminating pre-setting on site.
The FCM 106 can be used in stand-alone systems with
traditional control signals, such as start/stop signals, speed
references and closed loop process control or in multiple
drive systems with control signals distributed by a field
bus.
Combined fieldbus and traditional control signals with
closed loop PI control is possible.

No cabinet is required
The frequency converter is mounted directly onto
the motor, instead of connecting via the motor
terminal box
Electrical installation involves mains and control
connections only. There is no need for special
details on wiring to meet the EMC directive, since
motor cables are not necessary.
